man tonegen (1): Test the Voicetronix programmable tone generator

SYNOPSIS

tonegen [options]

The tonegen utility uses the programmable tone generator to send tones to some port.

The following options are available:

--card number: Explicitly select the card to test. Default is card 0.
--port number: Explicitly select the port to test. Default is port 0 of the card being tested.
--toneid num: Play a locale specific predefined tone, where 0 <= num < VPB_TONE_ID_MAX. The locale is decided according to the value of the VPB_COUNTRY environment variable.
--tone n freq mag: Set a single component for a user defined tone. This option may be used more than once with different values of n to set the components of a multi-frequency tone. Legal values for the other parameters are 0 < freq <= 4000 (Hz), and -inf < mag < 0.0 (dB).
--ontime ms: The number of milliseconds that a user defined tone should be on for.
--offtime ms: The number of milliseconds that a user defined tone should be off for.
--dial digits: Generates a dial string using the specified dtmf digits.
--sync: Play tones using the synchronous api functions. The default is to use the async api.
--loop: Loop cadenced tones continuously. Has no effect if a continuous tone has been specified.
--recgain db: Set software record gain in dB. Default is 0.0
--rec file: Record audio to a file while playing.
--contest: Do not wait for a tone to complete before starting the next one. This can be useful for stress testing the coherency of the tone generator.
--help, -?: Show summary of these options.
